An Oil Spill is a release of crude

oil into the environment. This is

cause by the human activity and it

is a form of pollution. Most of the

Oil Spills are cause in the ocean

that gets the name of marine oil

spill.

This Oil Spills affects, seriously,

our earth, our water, our animals,

and us.

In this experiment we want to

show you how hard it is to clean

contaminated water.

What is going to happen is that we

are going to clean the

“contaminated” water with several

sorbents.

We expect to clean it but not

completely.

We really need water and it is

really difficult to clean it from an

oil spill. We have to take care of it.

DAMAGE

To prepare the fresh water:

1. Fill baking dish with cold tap water to within 1 cm of rim.

2. Add 5-6 drops of food dye.3. Mix dye and water with a

stirring stick.4. Let solution settle.5. Answer question 1 in

Observations.

To simulate crude oil:

1. Place 3 tbsp. of vegetable oil in mug.

2. Add 2 tbsp. of cocoa powder.

3. Mix cocoa powder and oil thoroughly with a popsicle stick.

To contaminate fresh water:

1. Very slowly pour simulated crude oil from a height of 1 cm onto the top of the fresh water dish. If you pour the oil too quickly, the experiment won't work - start over!

2. Wait 3 minutes.

To test the sorbents:

1. Place a small sorbent sample into the centre top of the contaminated fresh water

2. Remove sorbent with tweezers or tongs.

3. Repeat step 1 with other sorbent samples.

Repeat all of the above procedures

substituting an ocean for the fresh

water. To prepare the ocean, follow the

fresh water procedures except add 1

tsp. of salt and mix it with the water

You need:

one 28 cm x 19 cm x 4 cm clear glass baking dish (or equivalent)

water blue food colouring 12 tbsp. vegetable oil 8 tbsp. pure cocoa powder 1 tsp. table salt a tablespoon a teaspoon 5 popsicle sticks a coffee mug sorbents (paper towel,

cotton balls, rag, string, nylon pot scrubber, sponge, styrofoam cup, garden peat moss, Shredded Wheat,)

1 squirt of liquid dishwashing detergent

tweezers or tongs bird feathers (available at a

pet store).
